3-6 Analog Audio Channel Recording and Playback

3-6-1 Signals Recorded on the Analog Audio Channels

Analog audio channels A1 and A2 record the signals
input to the ANALOG A1/A2 INPUT connectors on
the rear panel of the PCM-3348HR.
You can use these recorded signals for cuing during
editing.
Note
To increase the signal-to-noise ratio, the analog audio
channels use a compander. Therefore, in order to
record a pulse signal, it must meet the following
conditions.
• Pulse width (attack time plus margin): 5 ms minimum
• Pulse cycle time (release time): 13.5 ms maximum
